If the government was serious about this target, it would have backed it with policies: a thermal ban, a higher carbon price to drive existing thermal generation out of the market, mandatory renewables certificates to provide an additional revenue stream, or feed-in tariffs for wind to provide security for investment. Instead, they rolled back those policies, revoking the thermal ban and crippling the ETS. To the extent we've had progress at all, its only because Tiwai Point is threatening to shut down - and that's a mixed blessing because it has also stalled new investment.

But the fundamental problem is that the government doesn't care. Sure, they'll set a renewables target - but like their climate change targets, it'll be far in the future, when current Ministers expect to no longer be in government and therefore cannot be held to account for their failure to meet it. IBGYBG - and someone else will be left to clean up their mess.
